Trump had the idea of putting a import duty on all Chinese goods. It brought in hundreds of billions. Naturally, Biden and Democrats did away with it. Trump's plan would work but the problem is a long term one. It's not paying down the debt. It's overspending and incurring more debt. There could be many ways to pay down the debt but to stop incurring more in the future is where the real fix is needed. There should be a constitutional balanced budget amendment that cannot be abridged. No continuing resolutions, no kicking the can down the road.
